Perhaps I can assist with two of the vehicles: Bremerwagen III, und the Benz-Bäuer Kraftprotze.

The latter vehicle had successfully completed all trials in the Black Forest and was scheduled for production; only 3 were built. The Armistice halted all further development and production of either vehicle.

A vehicle you haven't listed was the Dür-Wagen; a clear improvement over the earlier A7V-Geländewagen, which too was ready for mass production when the war ended.
